pack mentality question

pack mentality passive ability mandates that i have all monsters in my paradigm pack be the same type in order to grant the user a boost.

however, do i need three monsters in my paradigm pack to activate it? if i only have one, won't it activate by default because since it is my only monster all my monsters are technically the same type?

if not, what do they mean by same type? same role?

thanks in advance for the help---the official kankuro of the nuns3 board psn: judefakoyen10
